59 <br /> lib <br /> Table 6 describes LOS criteria relating to average travel speed(ATS) and percent time-spent following(PTSF)for Class I <br /> facilities.PTSF can have a significant impact on LOS when there are few opportunities to pass slower-moving vehicles, <br /> typically because of sight-distance limitations. <br /> Table 6: Level of Service Description for Two-Lane Highways <br /> Level of Class I Highways <br /> Service ATS (mph) PTSF(%) <br /> A >55 <=35% <br /> B >50-55 35%-50% <br /> C >45-50 50%-65% <br /> D >40-45 65%-80% <br /> E <=40 >80% <br /> F Flow rate exceeds Flow rate exceeds <br /> segment capacity segment capacity <br /> Table 7 summarizes the results of HCS capacity analysis by segment and direction for the AM and PM peak periods.In <br /> general,LOS is slightly lower in the AM peak due to a combination of higher volumes and more pronounced <br /> directionality. <br /> The sections in Segments A,B,C, and D operate at an acceptable LOS in both directions during both peak hours.The <br /> section from US 70 Business to Pleasant Green Road in Segment E operates at an acceptable LOS in both directions during <br /> the PM peak hour and in the eastbound direction during the AM peak hour.This section operates at LOS E in the <br /> westbound direction dulrylrryling4 cptchCpe AM peak hour. <br /> ¢�I4RI4RI4��R�414�144144k4�a�.. <br /> 57 US 70 Multimodal Corridor Study Existing Conditions Report <br />
